Toss my old weights?

[Weiser_Cain]

No big deal to the pros but I’m now able to curl and do full sets with the 40lb dumbbell that use to gather dust under my desk, where as before I could barely squeeze one curl out with my strong arm just this January. Should I move on to heavier weights and toss the old thing? Or is there some merit in continuing to train with the same weight?

wait until you can easily complete 3 sets of more than 12 reps

it depends on your goal/s?

Why not keep them and use them for other exercises?
Or instead of tossing them sell them on craigslist.

why not keepo the 40lbs weight, and get a heavier one as well.
Perhaps more than biceps curls in your next program if you would like to see some good results.
